wlNoow FRAME AND SASH;

SPECIFICATION forming part of Letters Patent No. 738,491, dated September 8, 1903 Application filed October 6, 1 902. Serial No. 126,104. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES B. SOI-IILLING, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in WVindow Frames and Sashes, of which the following is a specification.

The main objects of my invention are to provide an improved form of fireproof window frame and sash, to provide an improved form of swinging sash having suitable means for securing same into a plurality of diiferent positions, to provide improved means for automatically locking same in its closed posi tion, and to provide improved means for causing the closing of the sash in cases of fire in the immediate vicinity of same. I accomplish these objects by the device shown in the accompanying drawings, in which Figure 1 is an elevation of awindow frame and sash constructed according to my invention, showing same in its closed position, as seen from the interior of the building. Fig. 2 is a vertical section along the line 2 2 of Fig. 1, showing the upper sash swung to an open position. Fig. 3 is ahorizontal section, partly broken away, along the line 3 3 of Fig. 1. Fig. 4 is a horizontal section, partly broken away, along the line 4 4 of Fig. 1. Fig. 5 is an elevation of one of the bracket-plates by means of which the sash is'pivotally connected to the frame. Fig. 6 is a side elevation of the latch which serves to hold the sash in its closed position.

The device shown consists of a sheetmetal preferably made of the shape shown, providing a shoulder 11, which serves as a stop for the lower part of the sash 7 and having in its under side a groove 12, which extends along the entire length of the bar 10. The bottom A cross-bar extends transversely.

bar 13 or sill of the sash is provided with a groove 14, corresponding in location to the groove 12 of the cross-bar 10. The groove 9 in each of the frame-bars 8 and below the cross-bar 10 is filled by a sash-bar 15, the transverse section of which is best shown in Fig. 4E. The bar 1.5 consists of a piece of sheet metal bent to a channelshaped section, as shown, and bent upon itself to form a flange 16, which serves as a stop extending along one edge of one face of the window-pane 17. The pane 17 is seated in the grooves 12 and 14 of the frame 5 and is confined against the stop 16 by means of strips 18, which are removably secured to the bars 15, as shown.

The sash 7 loosely fits the upper opening of the frame 5 and is pivotally secured to the side bars 8 of said frame by means of the pins 19, which are rigidly secured to the bars 8. Reinforcing-plates 20 aiford the required local strength. The side bars of the sash 7 are preferably constructed of two parts-the main part 21 and the member 22, which is slidably secured to the part 21 by having its curled edges 23 engaged by the curled edges 24 to the part 21. Each of the members 22 has rigidly secured thereto, at a point slightly above the middle of same, a plate 25, which is provided with a suitable aperture 26 for engaging the pivot 19. The plate is also provided with a flange 27, which extends alongthe face 28 and is secured thereto by means of screws 29, which are tapped into a reinforcing-strip 30, suitably located on the interior of the face 28.

The groove 9 in the bar 8 of the frame 5 and adjacent to the sash 7 is filled by a bar 31, which is constructed of sheet metal and is bent upon itself to form the flanges 32 and 33, which serve as stops to the sash 7 when same is in its closed position. The flange 32 extends along one side ofv the bar 9 from the upper end of same to a point 3a, near the pivot 19. Similarly the flange 33 extends along the other side of the bar 9 from its lower end upwardly to a point near the pivot 19.

The lower bar 35 of the sash 7 is provided with a catch which is adapted to lock said sash in its closed position. Said catch consists of a bracket 36, to which a latch 37 is pivotally secured. The latch 37 is weighted, so as to normally assume the position shown. by the shown at 37" when the sash is closed.

'prevent the latch 37 from falling below the position 37 said latch is provided with a shoulder 38, which engages the bar 35 and limits the movement of said latch. The latch 37 is also provided with a hook or shoulder 39, which engages the face 40 of the bar 10 and secures the sash 7 in its closed position. The surface 41, which is in advance of the shoulder 39, is suitablycurved to cause the raising of the latch 37 when brought into engagement with the upper edge of the shoulder 11 on the cross-ba r 10 of the frame 5. A chain 42 passes over the sheave 43 at the up per end of the sash 7 and has one end secured to an eye 44 in the latch 37. The other end of the chain 42 is provided with a plurality of large links 45, which are adapted to engage a hook 46 on the sill 13 of the frame 5. The sheave 43 is journaled upon a pin 47, which is secured by means of a suitable bracket 48 to the top bar 49 of the sash 7. The pin 47 is preferably constructed of fusible material and is adapted to fall and release the chain 42 when subjected to a certain high temperature, such as would occur in the case of fire near said sash.

The operation of the device shown is as follows: During the construction of the device the various parts of the frame 5 are assembled in their respective positions,as shown in Figs. 1 and 2. The sash-bars 15 are then placed in the grooves 9 below the cross-bar 12. The pane of glass 17 is inserted into the groove 12 and moved upward into same until its lower edge may pass into the groove 14 in the sill 13. The pane 17 is then lowered to the bottom of the groove 14 and is securely clamped against the flanges 16 by means of the fastening-strips 18, which are securely screwed to the adjacent bars 15. The bars 31 are now placed within the grooves 9 and above the cross-bar 10. The plates 25 are now securely riveted to the members 22, and the members 22 are slid into their approximate position with respect to the parts 21 of the sash 'Z. The sash 7 is now placed in position between the bars 31 and secured in such position by means of the pivots 19. The members 22 may now be shifted slightly longitudinally of the parts 21 of the sash 7 until said sash will turn freely upon the pivots 19 and properly fit between the bars 31. The flanges 27 of the plates 25 are now secured to the adjacent parts of the shaft by means of the screws 29. These screws securely fasten the members 22 against further movement longitudinally of the parts 21. This adjustment of the members 22 with respect to the parts 21 simplifies the work of perfecting the alinement of the pivots 19 and the lit of the sash within the frame during construction. WVhen it-is desired to open the upper sash, it is only necessary to pull upon the chain 42, and thereby lift the latch 37. Continued pull upon the chain 42 tends to pull. the upper end of the sash outward from the frame, asshown in Fig. 2. The sash may be secured in any of its open positions by passing one of the links 45 over the hook 46.- If the chain 42 is now re leased from the hook 46, the weight of the sash will cause same to close, and the weight of the latch 37 will cause the same to fall to its lowest position, and thereby secure the sash 7 in its closed position, as indicated by the dotted lines and marked with referencenumerals having double accents in Fig. 2. In case of fire near the sash 7 when same is in its open position the pin 47 will melt and fall under the strain upon the chain 42, and will thus release the sash and permit same to assume its closed position.

It will be seen that numerous details of the construction shown may be altered without departing from the spirit of my invention. I therefore do not confine myself to such details except as hereinafter limited in the claims.

What I claim as my invention, and desire to secure by Letters Patent, is-

1.
